Research draft, second pass
A second pass drafted this model: the structure a model of this thing needs, and what is known about it in the world. The line under this one says how the second half was obtained - researched against sources, or recalled without web access, in which case nothing here was read anywhere and every claim is a lead to verify.

Purpose and description
Enable an agent to recognise an electric lighting device, assess its illumination and operating condition, and determine compatible, safe uses and interventions.
An electric light is a device that converts electrical energy into optical radiation intended to provide illumination, commonly through incandescence, gas discharge or semiconductor electroluminescence.
It can be Identify the lighting-device boundary and classify its light-generation technology.; Compare candidate lights by output, distribution and colour under stated operating conditions.; Check documented supply, socket, driver and control compatibility before connection.; Switch or adjust illumination through supported controls and verify the resulting emission.; Assess abnormal output, heating or starting behaviour and determine whether isolation or service is required.; Select documented replacement components and an appropriate end-of-life handling route..
Distinguishing features
The device uses electrical energy to generate visible light for illumination; a reflector or diffuser alone does not qualify.
Illumination is an intended function, rather than incidental glow from a heater or an indicator on another device.
A replaceable source and a complete luminaire are distinguished by whether mounting, protection, optics and power conversion belong inside the recorded boundary.
An electrically powered device that emits only infrared or ultraviolet radiation falls outside this proposed visible-light scope.
Technology, connector and control interface describe variants of electric light without turning each product model into a separate kind.
